Re: To install a small program from a web browser

But he still wants to install programs

without knowledge to the users of his membership site (and no it's not a pornography site...I don't do pornography sites).

Let me paraphrase that. He still wants to circumvent the users security, and install programs without their knowledge. Incase I haven't been quite clear so far, let me spell it out. He wants to commit a crime. In assisting him to do so, you will be an ascessory to his crime. Circumventing the security of his members ( unless his members == his employees, and he owns the computers his employees use ) is a serious offence, and one which you should have no part in.
